Explanation:
Space Shuttle Challenger jumps off the launch pad
in 1985 to begin a successful mission. The
main purpose of
this mission was to test a new space based
laboratory named
Spacelab 2. Spacelab 2 takes advantage of the
effectively weightless conditions in orbit
to carry out experiments in areas such as astronomy, physics,
life science, materials science, and atmospheric physics.
Challenger and her crew were lost in 1986 when a booster failure
resulted in the breakup of the vehicle.
Previously, Challenger and her crews flew nine successful
Space Shuttle missions and made significant contributions to
America's scientific growth.
